A calm expense tracker for iPhone and Android. Log what you spend, watch the month take shape, and follow your net worth over time — with no accounts, no ads and no tracking of any kind.
Free · iOS 26.5+ · Android 8.0+
No sign-up, no servers of ours, no analytics. MoneyTurtle works entirely offline — and on iPhone it can sync through your own private iCloud if you want it on more than one device.
Add an expense in a couple of taps, and the rest of the app fills itself in — the month view, the calendar, the analytics and the net-worth history.
Every expense grouped by day, with a budget hero for the month and a calendar that shades each day by how much you spent.
Category breakdown and drill-down, month pace with a projection, biggest expenses, category movers, year-over-year and spending trends.
Track assets and liabilities over time on a dashboard, with a chart of how your net worth has moved month by month.
Create, rename, reorder and colour categories and subcategories so they match the way you actually think about money.
Optional app lock with Face ID or your passcode on iPhone, and biometrics or device credential on Android.
Work in the currency you use, and export everything to open JSON at any time — the same format on both platforms.
"Spent this month" and "Net worth" widgets on both platforms, so the number you care about is there without opening the app.
A design built for both, that follows your system appearance or stays on whichever one you prefer.
MoneyTurtle is written natively for each platform — SwiftUI on iPhone, Jetpack Compose on Android — and every screen exists on both. The JSON export is shared, so your data can move between them.
MoneyTurtle collects nothing. There are no servers of ours, no accounts, no analytics and no ads — your expenses, categories and net-worth entries live on your device, and on iPhone in your own private iCloud only if you turn sync on.
